I just did some of my own learning 2 weeks ago to help HS Students. I found the CoSpaces API pretty good once you find your way around. The Script also has API suggestions now while typing which helped me a lot.
Start the by right clicking the item and grabbing the ‘Scene.getItem()’ and setting it to a variable. The AutoFill will set it as an Animated Item. All the Animated Item methods can be found on this page: https://cospaces.io/api/classes/animateditem.html
The animation section will teach animations playing and stopping, The transform section teaches positions. The Transitions teaches movement code. OnCollisionEnter/Exit is there too on this page, as well as speech/thought syntax.
This is where it started to make more sense to me.
